8PECIFIGATION forming part of Letters Patent No. 659,528, dated October 9, 1900. Application filed December 28, 1899- berial No. 741,838. (No model.

To all 11/72/0717, it may concern:

Be it known that I, MONROE HOAGLAND, a citizen of the United States, and a resident of Henderson, in the county of Henderson and State of Kentucky, have invented a new and Improved Fifth-Wheel, of which the following is a full, clear, and exact description.

This invention relates to a vehicle fifthwheel, the construction of which is such as enables it to be placed rearward of the front axle, thus mounting the front axle so that the vehicle may be turned much shorter than would be possible were the center of movement coincident with the longitudinal line of the axle.

This specification is the disclosure of one form of myinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of the invention. Fig. 2 is a plan view of the same. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a front elevation of the invention. Fig. 5 is a bottom plan view of the fifth-wheel cap or top section with its attached parts. Fig. 6 is a top plan of the lowersection of the fifthwheel, and Fig. 7 is a bottom plan of the same.

The axle 8 has a wear-block 9 attached rigidly to the top at the middle thereof by means of clips 10, which engage the front ends of arms 11, thus rigidly mounting the arms in place. These arms extend rearward of the axle and carry the lower section 12 of the fifth-wheel. This section 12 is in the form of a disk or wheel and is constructed on its top face with two segmental raised portions 14, forming bearings. The section 12 is also constructed at each side with recesses 15 in its edges.

Arranged to slide on the wear-block 9 is a corresponding block 16, to which should be attached the springs of the vehicle, whereby to connect the block 16 with the vehicle through the medium of the springs, as will be understood. To this block 16 the two reach-sockets 17 are rigidly attached in any desired manner, and in the sockets the reaches 18 are fastened. The top section 19 of the fifth wheel is secured rigidly to or formed integral with the reach sockets 17, so that the parts 16, 17, and 19 are practically one rigid structure. The section 19 of the fifth-wheel has downwardlyprojected bearing portions 20, respectively riding on the portions 14 of the section 12 of the fifth-wheel. The section 19 is also constructed with an annular flange 21, extending entirely around its edges, such flange receiving the lower section 12, as shown best in Fig. 3. This flange 21 has inturned lips 22 of such size and form that they may be passed transversely of the section 12 through the recesses 15 thereof and then the sections 12 and 19 moved relatively a quarter-turn, so as to bring the lips 22 out of registry with the recesses 15, thus locking the two parts of the fifth-wheel together in such a way that they may turn, but preventing their disengagement from each other. The section 19 of the fifth-wheel has a centrally-disposed boss 23 formed thereon,which projectsthrough a central opening in the section 12 of the fifthwheel and which has secured thereto a pivotbolt 24, which serves to hold the sections of the fifth-wheel engaged. It will be seen, therefore, that I mount the front axle to turn on a center located rearward of the axle, and thus I am enabled to turn the vehicle much shorter than otherwise. It will also be seen that owing to the special form of the fifth-wheel sections they may be readily engaged or disengaged when it is desired to assemble or separate the parts of the vehicle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a vehicle, the combination of an axle, a bolster mounted thereon, arms rigidly attached to the under side of the axle and projected rearward of the same, a lower fifthwheel section carried by the arms, an upper fifth-wheel section mounted on the lower fifthwheel section, reach-sockets fastened to the bolster and to the upper fifth-wheel section, and reaches fastened in the reach-sockets.

2. In a vehicle, the combination of an axle, a bolster mounted thereon, arms attached to the under side of the axle and projecting rearwardly, a lower fifth-wheel section carried by the arms and comprising a disk with oppositely-disposed recesses in its edges, an upper fifth-wheel section having peripheral flanges with inwardly-tn rned lips adapted to pass through the recesses in BhGiIONVGIwfifflhwW-IIQQI section and engage with such sections. reachsockets fastened to the bolster and to the upper fifth-wheel section, to carry the same, and reaches fastened in the reach-sockets. 3. In a vehicle the combination ofanA-axle, l a bolster mounted thereon, arms attached rigidly to the axle and projecting rearwardl'y, therefrom, a lower fifth-wheel section carried by the arms and comprising a disk with 0p-- positely-sitnated ,penipheral ,lta esses, ,reachsockets fastened to the bolster, an upper fifthwheel section carried nnder thereaeh soclmts and comprising adisk with a peripheral flange ,inclosing the lower fifth-wheel :sectionmnd having oppositely-situated intunned ilipslea- V pableiof passingthrough tthe reeesses intthe lower fifth-wheel section,.means forliiastening the fifth-wheel sections to ,penmititherelative turning thereof, and reaches carried in the fifth-wheel soeket.

4. In a fifth-wheel mechanism for vehicles, the combination of arms provided with means for rigidly securing them to the axle, the arms extending rearward therefrom, a lower fifthw heellsection :oarriefl :byithe arms, an upper fifth-wheel section mounted on the lower fifthwheel section, and reach-sockets adapted to be fastened to the bolster, the reach-sockets carrying the upper fifth-wheel section on their -under sides and projecting rearward therefrom to rece'ive the reaches.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. v
